46 Claims.

This invention relates to machines for securing work-parts by theinsertion of fastenings, and is herein disclosed as embodied in amachine for attaching heel-parts to shoes in a manner similar to theapparatus of Letters Patent of the United States No. 2,207,742, LaChapelle, July 16, 1940, which employs fastenings severed from stringsof fiber, or the like.

It is an object of my invention to improve the operation of suchmachines as that of the patent, and to render them more convenient forthe operator. In the attainment of this object, the following featuresare involved. The pressure which the operator may apply to the work inholding it for the insertion of the fastenings is limited to apredetermined amount. This is of particular utility in connection withsuch readily compressible parts as rubber lifts or heels. The adjustmentof the extent of movement of the fastening-inserting drivers isfacilitated. In heel-attaching, this is useful in changing fromrubber-work to leather-Work. In the use of fiber fastenings, the partsto be secured are pricked by the drivers before the inserting stroke,and, as in the preceding feature, this is made easy for the operator.The form of the Work may render it desirable to prick less deeply forthe fastenings over some areas, than other others. This I effectautomatically under the control of mechanism for transferring fastenersto the inserting mechanism. There is provided a heelor other Work-holderarranged for ready interchangeability to present articles of difierentsize for the inserting operation, and which allows for the substitutionof Work-engaging portions of the fastening-inserting mechanism. Forchanges in the inserting design, adapting means is placed between thefeeding mechanism and transferring mechanism, so, with minimum effort,the operator may direct the strings of material from a constantarrangement of passages at the feeding mechanism, to differentlyarranged groups of passages in which the fastenings are transferred tothe inserting mechanism. As the work is pricked to different extents,when its thickness changes, the length of the fastening material fed iscorrespondingly varied, and, to give the fastenings better holding poweras they are compressed in driving, I advance an excess offasteninglength over the depth of pricking, this excess beingproportionate to the variation in length.

In the accompanying drawings,

In its general characteristics, the present machine resembles that ofthe above-mentioned patent. There is, however, but a single workprickingand fastening-inserting mechanism M, with its fiber-shearing and-loading mechanism L. The features common to the two machines will bebut briefly described. The work, as a shoe S to be heeled (Fig. 2), issupported upon a jack J beneath a die and abutment l8 of the mechanismM, with which die is associated a holder H retaining against theunderside of the die a toplift 2, which may be of rubber, and, belowthis, a heel-base h. The heel-seat of the shoe is brought intopreliminary engagement with the heel-base in the holder by actuation ofa treadle l2, and receives final work-clamping pressure under theciprocatory drivers I 4 of the inserting mechanism M act, throughfastening-receiving passages II in the die, to first prick through theheel-parts and into the heel-seat of the shoe, and, upon a secondmovement, to insert fastenings in the pricked openings. These fasteningspreferably consist of lengths cut from strings of fiber J (Fig. 8),advanced from feeding mechanism F to the loading mechanism L. Thefeeding mechanism is operated, under the influence of the prickingstroke of the drivers I 4, to advance the correct lengths of the fiberstrings into the passages in the loading mechanism. Said loadingmechanism then acts to shear ofi discrete fastenings and transfer theseabove the die-passages, presenting them to receive the inserting strokeof the drivers.

Considering the work-support or jack J, this may be as before, but animproved mechanism is provided for elevating it and the work intoengagement with the die ll], together with means whereby the pressureapplied through the treadle l2 may be limited. By this means is avoideddistortion of rubber lifts, if excessive force is applied by theoperator. Referring to Figs. 1, 2, 3 and 7 of the drawings, a bracketI5, upon which,

the jack J is slidable horizontally, has at its underside a block I6guided for vertical movement in the frame H of the machine, and isprovided with a vertical threaded bore receiving a screw I8 rotatableupon a second block 26, also movable vertically upon the frame. A cam 22upon the driving shaft I3, through the just indicated connections,applies final clamping pressure to the jacked work against the die.Engagement of the Work with the die has previously been effected to givepreliminary pressure through the following connections to the treadleI2. This treadle projects from the lower, extremity of a slide 26,guided in vertical ways in a transmitting slide 26 movable in similarways in the frame (Figs. 3 and 7). In the slide 26 is a vertical bore,in which is a compression-spring 36 resting at its lower extremity upona forward projection 32' from the slide 28. Between the bottom of theslide 26 and the projection 32, there is a space so said slide may movedown, compressing the spring. A weight 34 (Fig. I), joined to the slide28 by a cable 36 running over guide-rolls 38, 36 upon the frame, holdsthe treadle normally raised. Fast upon the screw I8 is a pinion 46, withwhich meshes a rack 42, guided for horizontal reciprocation upon theframe. Also meshing with the rack is a pinion 44, secured to a verticalshaft 46 journaled in the frame. The shaft 46 has fast upon it a spiralpinion 48, which meshes with a spiral rack 56 movable in a verticalguide 52 attached to the frame. The rack is joined by a link 54 to theslide 28. A horizontal extension from the rack, to which the link isconnected, may engage the lower extremity of the shaft 46 to furnish astop for the upward movement of the slide 26 and the treadle. Guided formovement transversely of the machine in horizontal ways in the slide 28are opposite blocks 56, 56, the outer sides of which have at their innerextremities downwardly and inwardly inclined ribs 56, movable incorrespondingly inclined grooves 59 in the adjacent inner wall of theslide 26. At the outer extremities of the blocks are vertical series oflocking teeth 66, which, when brought into engagement with opposedVertical series of teeth 62 upon the frame I'I, secure the slide 28against downward movement. With downwardly and inwardly inclinedsurfaces 64 at the inner ends of the blocks, contact complementallyinclined surfaces 66 upon a wedge 68 attached to the slide 26.

When the operator depresses the treadle I2, the slide 26 is lowered,and, without compression of the spring 36, causes the depression of theslide 28, the teeth 66 upon the blocks 56 being at this time held awayfrom the frame-teeth 62 by the ribs 56 and grooves 59. As the slide 28descends, it draws down, through the link 54, the rack 56.

This, through the pinion 48, shaft 46 and pinion 44, shifts the rack 42,rotating the pinion 46 to turn the jack-screw I8. Said screw, actingupon the bracket I5, raises it with the jack. J to bring the workagainst the die I6. Upon establishment of this contact and continueddownward movement of the treadle, the spring 36 is compressed, the slide26 moving relatively to the slide 28. The surfaces 66 of the wedge 68,pressing against the surfaces 64 of the blocks 56, urge these outwardly,causing the block-teeth 66 to engage the frame-teeth 62, and locking theslide 28'to the frame. Consequently, further depression of the treadlehas no effect upon said slide and the connected jack, the compressionofthe work being limited by the degree of compressibility of the spring36. But when the treadle is released and elevated by the weight 34, thegrooves 59 and ribs 56 upon the slide 26 and blocks 55, respectively,cam these blocks inwardly to effect positive withdrawal of their teethfrom the frame-teeth. Because of this locking of the treadle, there islimited the preliminary pressure which the operator may apply to thework, and which, when added to the final pressure created by the cam 22,might be excessive.

The die I6 is interchangeably latched at I6 in the frame, and may haveits fastening-receiving passages II arranged in a multiple of theinserting designs which are to be employed. The drivers I4, whichco-operate with the passages in the die, are mounted upon a plate I4carried upon a top-girt 18 (Fig. 5). This top-girt is secured to theupper extremities of side-rods 66, 66, guided for vertical reciprocationin the frame and operated from the driving shaft I3. This may be, in themanner of the previously mentioned patent, through a work-prickingstroke and a shorter fastening-inserting stroke. To vary the extent ofdownward travel of the drivers to adapt the machine to operate upondifferent types of work, as the attachment of rubber lifts and leatherheels, the vertical. position of the driver-plate I4 is made adjustable.It is directly mounted in ways in a carrier-plate 82 and is separablylatched in place at 8|. The carrier-plate is guided for verticalmovement in the top-girt andhas extended transversely at its upper sideinclined ways, along which a Wedge 84 is movable (Fig. 4). At its upperside, the wedge may be shifted along horizontal ways in the top-girt.This is effected by a screw 86 threaded into the wedge and being heldagainst longitudinal movement by the extension of a hand-wheel 88,fastened upon it, into a recess at the underside of the top-girt. Byrotating the hand-wheel and thus moving the wedge, the carrier-plate,driver-plate and drivers may be raised or lowered, and the plane inwhich the inserting travel of the drivers terminates similarly altered.

To vary conveniently the depth of the pricking stroke of the drivers I4,the top-girt I6 has a vertical extension 96, across the upper portion ofwhich is secured a contact-plate 92. At the opposite sides of theextension are vertical ways, in which a slide 94 is guided. Movabletransversely in ways at the bottom of the slideis an eccentric-strap orblock 95. Fitting within an opening in this block is an eccentric 96,fast upon the inner end of a spindle 98 rotatable in a bridge I66between the opposite sides of the frame, said bridge being located infront of the side-rods. Secured to the outer end of the spindle, is ahand-crank I62 carrying a locking pin I64, which may enter any one of acircular series of openings I66 formed in a disk I66 attached to thefront of the bridge. Upon the slide 64, in vertical alinement with thecontactplate 92, a cushion or bumper II6, of yieldable material, iscarried. As the drivers make their downward pricking stroke, the platemoves into engagement with the cushion, stopping the de-. scent of thetop-girt and, therefore, of the drivers. Thepoint at which this occurswill depend upon the vertical position of the cushion. This isdetermined by the angular adjustment of the eccentric 96, controlled bythe disk-opening I66 in which the plunger I64 has been placed by theoperator. The range of adjustment may be increased by substitutingcontact-plates of different thickness. There may be associated with theopenings in the disks, designations showing the depth of pricking whichwill result from the positioning f the eccentric by the use of aparticular opening.

Some of the drivers I4, as those inserting the fastenings nearest thebreast of a heel, operate over areas of the heel-seat which areconsiderably curved outwardly. For this reason,

it is desirable that the depth of insertion, and therefore the prickingstroke, shall be less than that of the companion drivers. When, however,the inserting stroke of the drivers is made, they should all advance tothe same plane to correspondingly locate the outer ends of thefastenings. Referring particularly to Fig. 4 of the drawings, the twobreast-drivers are carried by a secondary plate H2, guided for verticalmovement at the front of the primary plate I4. At its upper side, theplate II2 has a T-projection II4, guided in complemental ways in anadjusting wedge II6 provided with opposite projections H8, H8 movable inupwardly and rearwardly inclined ways in the plate I4. Anexpansionspring I urges the wedge outwardly, to so occupy the spacebetween the plates I4 and H2 as to hold down the latter.

Upon the inner side of a door I22, hinged upon the frame and normallyclosed as a guard for the inserting mechanism M, a vertical plate I24 ispivotally supported upon arms I26, I26, it being urged inwardly by aspring-actuated plunger I28 slidable horizontally in the door. With thedoor closed, the plunger forces the plate against a roll I30, rotatableupon the forward end of the wedge IIG, this being carried rearwardly andupwardly in its inclined ways against the force of the spring I20,elevating the plate II2. As a result of this, the breast-drivers areraised to prick the work less deeply over the outwardly curved portionof the heel-seat. Rotatable upon the lower edge of the plate I24 is aroll I32, which lies in the path of the loading or fastening-deliveringmechanism L, when this advances to make its delivery to the die I0.During the pricking stroke of the drivers I4, the loading mechanism isretracted, as appears in Fig. 4, and does not engage the roll I32, sothe plate is held in its advanced position by the plunger I28 and thewedge H6 is forced back, as above described. During the inserting strokeof the drivers, the loading mechanism is forward over the die, at thistime acting upon the roll I32 to carry back the plate I24 against theforce of the plunger I28. The plate is thus withdrawn from thewedge-roll I30, and the spring I20 forces the wedge forward, loweringthe plate H2 and the breast-drivers. This corresponds in verticalrelation to the other drivers, so the depth of insertion of the outerends of all the fastenings is the same. Because of the verticalextension of the roll-engaging surface of the plate I24, it exerts itscontrolling influence upon the wedge IIB, regardless of the verticaltravel of the wedge-carrying driver-plate I4.

It may be desired to attach with this machine either heel-lifts ofleather, or the like, or yieldable lifts of rubber. In the firstinstance, the die I0, at its underside, should present a smooth surfaceto the work. In the second, it is preferable to have upon the diefrusto-conical projections I33 about the lower openings of the passagesI I, these either seating in the usual depressions in the tread-surfaceof the lift, or, in absence of these, entering and compressing theyieldable material. I satisfy these conditions by the application to thedie of interchangeable contact-plates, one of which is shown at I34 inFigs. 4 and 5 of the drawings. The one illustrated has the projectionsI33, and at its opposite side-edges is received by dovetail grooves inthe die. It is locked in operating position by a spring-plunger I38movable in the die, and, when this plunger is raised from a depressionin the plate, may readily be withdrawn through a finger-piece I40 andreplaced by another plate. This may be one with a smooth surface forleather-work, and such smooth plates, or those with the projections,have openings corresponding to a particular one of the inserting designswhich are in multiple in the die.

With the underside of the plate I34 is associated the heelandtop-lift-holder H. To the die I0, at each side of the plate, is secureda retaining strip I42 supporting a horseshoe-shaped heel-ring I 33,which will receive between its arms a rubber lift, somewhat compressed,and hold this against the under face of the die. This heel-ring ishinged to the strips M2 in recesses I44, and is normally latched up inhorizontal position by a spring-plunger I45 mounted upon the forwardextremity of one of the supportstrips, and engaging the ring. Said ringhas a rearward extension i-il, upon which are movable about verticalpivots opposite forwardly extending arms M8, M8 for grasping betweenthem a heel-base. The arms are geared at I to move together, and aredrawn toward each other by a tension-spring I52 connecting them. Theholder H is used in the customary manner by inserting a rubber lift inthe rin and a base between the arms, it retaining one above the otherfor the driving of the fastenings through them into the heel-seat of thejacked shoe. When the plate I34 with the projections I33 is to beremoved from or applied to the die, the latch I is freed, and the ring I33 turned down in its pivot-recesses M l, so both the ring I46 and thearms IE3 are separated from the plate. This leaves clear a space beneaththe die, through which the projections I33 may move without interferenceduring manipulation of the plate I34. To permit the ring, with itssupported arms, to be changed for elements adapted to engage heel-partsof different sizes, the pivotrecesses I44 for the ring are downwardlyand forwardl inclined, being open at their lower portions (Fig. 4).Consequently, when the ring is raised and latched, it is retained inposition, but, when lowered, may be separated from the die forsubstitution.

The strings I of fiber, which furnish the fastenings, are taken fromunillustrated reels, which, to be convenient of access and formanipulation when the fastening-inserting design is changed, aresupported upon the upper portion of the frame, as are also the feedingmechanisms F, F (Fig. 5). These feeding mechanisms and their actuationmay be, except as to a detail which will be hereinafter considered, asin the previously mentioned patent, the fiber being advanced to theloader mechanism L step-bystep to an extent determined by the prickingstroke of the drivers I 4. This feed is produced by a pair of rolls I53,I53 (Fig. 8), geared together at I 54, and one of which is oscillatedthrough a link E55 connected to the top-girt I8 and to a reciprocatoryrack I55 meshing with a gear I51 on one of the roll-shafts. From therolls, the fiber passes through flexible tubes I58 (Fig. 4), the lowerextremities of which are inserted in Vertical passages I60 in afoot-plate I62. This footplate is attached to a vertical rod I64,movable in a guide member I66 and in an overhanging bracket IE8 mountedupon the frame, a horizontal extension of the bracket having passages 59continuing those in the footplate. Said foot-plate may be raised andlowered through a hand-lever I!!! (Fig. 5), fulcrumed at I'I2 upon theframe and pivotally joined to the foot-plate at Ild. To an arm I16 ofthe lever, a rod I78 is attached, this bein urged to the right by anexpansion-spring I80 to hold the foot-plate normally lowered. Dependingfrom the foot-plate and guided in the extension of the bracket I58 is alatch-pin I82, which may enter any one of a series of openings I84 (Fig.6) in an adapter-bar I86, which is guided in the member I85. The bar isprovided along its length with a plurality of spaced groups of passagesI88, arranged in accordance with the inserting designs which are to beemployed and which are herein shown as three in number. These groups ofpassages are inclined vertically to different degrees, but at theirupper extremities are identical in their relation, being arranged toregister with the passages I59 and I89. Included in the loadingmechanism L is a multiple fiber-shearing and -transferring block I90,containing groups of passages I92 for all the inserting designs. Theinclination of the barpassages I88 is such that one of each of itsgroups may be brought into registration with one of the multiple designsin the block I90. This block, as in the hereinbefore cited patent, isoscillated and reciprocated by slide-and-crank mechanism we to shear oilfastenings advanced by the mechanisms F, F, through the passages I58,I69 and IE9 into the block-passages 92 and convey these fastenings intoregistration with the die-passages II, to be inserted in the work by thedescent of the drivers I4. When the inserting design is to be altered,the strings of fiber are withdrawn from the passages in the bar I88, byturning a hand-wheel I98 (Fig. 4) upon one of the roll-shafts of each ofthe feeders F. Then, the lever Ill! is depressed and the foot-plate H52lifted. This frees the bar I86 from the latch-pin I82, so said bar maybe shifted longitudinally by a hand-hold 2% upon one of its extremities.When the chosen group of openings is in registration with the unvaryingpassages I69 and I58, as determined by a springclick ZBI carried by themember I65 and engaging one of three depressions in the bar, the releaseof the latch into the corresponding openings I84 again secures the bar.The inclination of its chosen group of passages correctly leads into oneof the groups of multiple passages I92 in the loader-block.

The operator may wish, as the feed of the fiber J is varied under thecontrol of the pricking stroke of the drivers I4, to proportionatelyincrease the excess of the length of the fastenings, which is to becompressed as the drivers complete the insertion. This, I accomplish bymaking the pitch-diameter of the gear I51 less than the diameters of therolls I53. Since, for any reciprocation of the rack lfit through adistance depending upon length of the pricking stroke of the drivers,the peripheries of the roll I52, turned by the smaller gear I51, willoscillate through an are greater in length than said pricking stroke,there will always be an excess of material fed to be compacted by thedrivers. Further, as the depth of pricking increases, there will be acor respondin lengthening of this excess. The fiber 75,

employed in this machine owes some ofits holding power in the work tothe fact that it is made by twisting a strip helically. This is as inLetters Patent of the United States, No. 1,729,169, La Chapelle,September 24, 1929. When the fastenings formed from it are inserted, thedriving pressure tends to untwist the helix, adding to its diameter.Therefore, with an increase in fastening-length, I obtain aproportionately greater force of retention, not only exerted by thepricking-controlled portion but also by the excesslength.

Let it be assumed that the apparatus is to be employed for theattachment to a shoe S of a leather base it and a rubber-lift Z, byfastenings severed from strings f of fiber. The operator makes certainthat there is mounted beneath the die It! a plate I34, havinglift-entering projections 833 with their passages arranged in thecorrect inserting design, the drivers I4 being similarly arranged upontheir plates I4 and H2. The adapting bar I86 is positioned to bring thecorrect group of its passages I88 into registration with thefoot-plate-passages I68 and the loaderblock-passages I92, thefoot-plate-projection I82 latching the bar in place. The depth of thepricking stroke of the driver is determined by adjustment of theeccentric 96 and the extent of the inserting stroke by that of the wedge84. The shoe is placed upon the jack J, and depression of the treadle I2raises the heel-seat into contact with the cup of the base it with apressure limited by the yield of the spring 3th Upon starting thepower-operation of the apparatus, the rotation of the cam 22 appliesfinal pressure to the work, and the drivers are reciprocated to pricksaid work. Then, the loader-block I 90 advances to shear fastenings fromthe strings I, which have been delivered from the feeders F through theadapting bar, and transfers them above the die I9. These fasteningsexceed in length the depth of pricking to permit their expansion in thework. Finally, the drivers are again reciprocated to carry thefastenings out of the loader block and insert them in the prickedopenings for the attachment of the heel-parts to the shoe. For these twostrokes, the breast-drivers are raised by the wedge IIB during prickingto act less deeply than their companions, and are then returned withtheir ends in a common inserting plane, and for both are definitelyfixed in position. With the return of the jack J to its normal position,the cycle of operation is completed, and the heeled shoe may be removedfrom the jack.
